Voice or Noise (Japanese: ボイス・オア・ノイズ, Hepburn: Boisu oa Noizu) is a yaoi manga series by Yamimaru Enjin, author of the one-shot manga The Way To Heaven and illustrator of the novel Eat or Be Eaten.

The story focuses on the relationship between a junior high school student, Shinichiro, and a college professor, Narusawa, both of whom have the ability to speak to animals.

For a time, Blu Manga held the licensing rights to publish the series in North America.

Blu Manga originally licensed the series for English-language publication in North America and released a total of three volumes.

With Tokyopop, the company in charge of distributing Blu label's releases, ceasing its activity in North America in 2011, however, the English-language publication of the series remained incomplete.
